LOCK.

Application filed September 19, 1923.

To all whom a may concern:

Be it known that l, JAMns herein, a citizen of the United States, residing at New .7 1 'L 4. *7 ioik City, in L118 county of New 101k and State of New York, have invented certain new and useful Improvements in Locks, of which the foilowing is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in looks and more particularly to a lock providing multiplicity of locking points for a door or similar closure.

An important object of the invention is to provide in combination with a door having a look, a pair of eyes one of which is carried by the door or closure and the other of which is carried by the jamb thereof, so that the eyes are brought into alignment by the closure of the door and means controlled by the bolt of the lock shifting an additional locking part to engage through the two eyes to lock the same together.

A further object of the invention is to provide a structure whereby a single locking mechanism effects the locking of not only a locking of the closure at a point intermediate its ends but the locking thereof at opposite ends. 1

A further object of the invention is to provide a combiner device of this character which is simple in its construction and operation, which will be durable in service and a general improvement in the art.

These and other objects I attain by the construction shown in the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of -my invention and wherein 2- Figure 1 is a vertical sectional view taken through a lock constructed in accordance with my invention;

Figure 2 is a section on the line 22 of Figure 1;

"Figure 3 is a section onthe line 3--3 of Figure 1;

Figure 4 is a section on the line 44 of Figure 5;

Figure 5 is a section on the line 5-5 of in the door 1s a thlrd plate or looking Figured;

Figure 6 is a detached perspective showing the parts of the auxiliary locking mechanism; and

Figure 7 is a view similar to that shown in Figure 5, the parts being shown in the unlocked position.

Serial No. 663,629.

Referring now more particularly to the drawings, the numeral 1.0 indicates a door or other closure, 11 the frame thereof, and 12 the jainb against which the door abuts in closing. Carried by the door and in the present instance shown as mortised in the door is a casing 13 within which are disposed a pair of meshing gears 14 and 15, these gears being supported for rotation and the gear 15 being adapted for key operation. One of the gears, in the present instance shown as the gear 14, carries a bolt 16 which is adapted to project through an opening of the casing to engage in a mortise 17 formed in the frame to lock the closure against movement in the usual manner. This lock is at present shown as pivoted to the gear 14, as at 113, the gear having a stop lug 16 limiting the pivotal movement of the bolt in one direction. Each side of gear 14 meshes with a rack 18 formed upon the end of a bolt 19, one of the bolts operating in a channel 20 and adapted when the bolt 16 is in a locking position to be projected to a position where it will engage in a socket 21 formed in the frame 11. In order that the bolts 19 may be vertically aligned the upper bolt is shown as being offset as at 22. It will be seen that upon rotation of the key operated gear 15 by the key not only will the bolt 16 be extended .to engage in its mortise but the bolts 19 will be extended to engagein their sockets there by locking the closure not only centrally but at the ends thereof.

In combination with this locking structure I provide a further locking structure gen erally indicated at 23. This locking structure consists of a pair of plates 24 and 25, the former carried by the closure and the latter carried by the jamb 12, each plate being rigid to that part upon which it is mounted. The plate 24: is provided upon one side adjacent its end edges with a pair of spaced eyes 26 and 27. The plate 24 is provided upon its side edge approximately centrally thereof with a pair of spaced eyes 28 and 29.

Slidably directed through a slot 30 formed part 31 having spaced abutment shoulders 32 and 38 over and underlying the bolt 16 respectively. At its outer edge the locking part 31 is provided with a pair of outstanding spaced lugs 34 and 35. The upper lug 34L is provided with a; downwardly projecting pin 36 and the lower lug has extending therethrough a. pin 37 the ends of which project above and below the lug. This lug operates between the eyes 28 and 29 of the plalte 24 and has its pin 37 at all times engaged in either one or the other of these eyes. When the plate 31 is in the elevated position the pin 37 is withdrawn so that no portions thereof project either above or below the eyes 28 or 29 of the plate 2%. lVhen in the lowered position the lower end of the pin 37 projects below the lower end of the lower eye 29 of the plate 24. The pin 36 of the upper lug when in lowered position enters the upper lug 28 of the plate 24: and when the plate 31 is in the elevated posit-ion clears the upper surface of this lug by a distance slightly greater than the depth of the eye. 26.

The operation of this port-ion of the lock is as follows: hen the door is being closed the bolt 16 is, of course, in the position shown in Figru'es l and 2 and accordingly the pins positioned so that the eyes 28 and 29 of the door carried plate 24 may enter between the eyes 26 and 27 of the jamb plate 25. After the door is closed, if the key is operated to shift the bolt 16 to the locking position, the bolt during its downward movement moves with it the plate 31 with the result that the pins 36 and 37 lock the eyes 26 and 28 together and the eyes 27 and 29 together. Thus the movement of the bolt accomplishes a double locking of the door intermediate its ends and the locking of the door at each end.

While I have in the present instance for convenience in disclosure shown the main lock and the lock 23 at the same level, it will of course be understood that these locking parts may be arranged at different levels, the plate 31 being extended to the desired length to efiect the operation. It will also be obvious that while in the present instance I have shown and described the device as employed with a door its use is not in any way restricted to structures of this character, for a lock of this character is capable of use as a desk lock or for sliding, swinging or rotating doors. Many changes being possible in the construction of the device as hereinbefore set forth without in any manner departing from the spirit. of my invention I do not wish to be understood as limiting myself to such specific structure except as hereinafter claimed. r

1. In a lock and in combination with a casement and closure coacting therewith, coacting eyes carried by said casement and closure, a lock carried by the closure and en gageable with 'the easement and having a bolt engageable with the easement, a pin normally engaging the closure carried eye, and a connect-ion between said pin and bolt shifting the pin to simultaneously engage the eyes when the bolt is operated to engage the easement.

2. In a lock and in combination with a' signature.
